12 · Telegram price bot

A grammY bot backed by hoodchain: /price AAPL reads a Chainlink feed, /trending lists the newest NOXA / Odyssey launches. Long- polling, no webhook, no server — deployable on any free-tier host (Railway, Fly.io, Render) or your own machine.

What it proves: a full user-facing bot is ~70 lines once the SDK does the chain work, and the read surface (getQuote, getRecentLaunches) is the same one used by examples 02 and 05.

Prerequisites

• Node ≥ 20.
• A Telegram bot token from @BotFather (/newbot, free, instant).

Run

npm install && npm install ../../../robinhood-chain-sdk
TELEGRAM_BOT_TOKEN=123456:ABC-your-token node index.js

Then message your bot /price AAPL or /trending on Telegram.

Verified behavior

Without a token, the bot fails immediately with a helpful message instead of hanging (tested):

✗ TELEGRAM_BOT_TOKEN is not set.
  Create a bot with @BotFather on Telegram, then:
  TELEGRAM_BOT_TOKEN=123456:ABC-... node index.js

Import and registry load were verified live:

grammy Bot: function
registry size 95

Live Telegram session: pending a bot token. This repo doesn't hold a Telegram bot credential, so the long-polling session itself (the actual /price reply screenshot) is the one piece not captured here — everything up to that boundary (SDK reads, grammY wiring, the failure path) is real and tested. Owner: run the command above with a @BotFather token to go live.

Deploy for free

Any Node ≥ 20 host works — set TELEGRAM_BOT_TOKEN as an environment variable and run npm start. No inbound port needed (long-polling), which is why this fits comfortably inside every major free tier.
